Description: This research was to determine the frequency and factors affecting disagreement between cardiologist (MD1 or MD2) and the computer assisted interpretation (CAI) of pediatric electrocardiograms from patients with congenital heart disease patients (CHD, n=586) or structurally normal heart (NOR, n=561).Significant disagreement was found in CHD (146/586, 25%) compared with NOR (64/561, 11%) (p &lt; 0.001). Kappa values for specific ECG diagnosis ranged from 0.71 to 1.0. CAI over interpreted prolonged QT, sinus rhythm with ectopy and right ventricular hypertrophy (RVH); CAI under interpreted sinus rhythm, sinus arrhythmia and right bundle branch block (RBBB) (p &lt; 0.05).Verification by an expert overreader remains crucial in CAI. The areas of CAI for improvements included rhythm diagnosis, RBBB, RVH and QT analysis.Disagreement was independently associated with CHD, younger patient age at time of ECG, more than 3 CAI statements and MD1 vs. MD2.
